Tuning fork terminal detection device

Abstract

The invention relates to the technical field of quality detection equipment and discloses a tuning fork terminal detection device. The detection device comprises a rack and a detection assembly installed on the rack in a sliding mode, wherein a detection platform is arranged on the rack, a clamping device used for clamping a part to be detected is arranged on the detection platform, a detection driving device installed on the rack and used for driving the detection assembly to do reciprocating motion in the vertical direction is arranged above the clamping device, the detection assembly comprises a detection assembly installation support, a plurality of probes installed on the detection assembly installation support in a sliding mode and sensors located above the probes and corresponding to the probes in a one-to-one mode, the sensors are electrically connected with the controller, each probe comprises a probe head and a probe body, the outer diameter of each probe body is larger thanthat of the probe head, and at least one side of each probe body protrudes out of an outer wall of the probe head. The tuning fork terminal detection device adopting the technical scheme of the invention is simple in structure, can automatically detect a plurality of tuning fork terminals, and is high in detection precision and efficiency.

Description

technical field [0001] The invention relates to the technical field of quality testing equipment, in particular to a tuning fork terminal testing device. Background technique [0002] The automotive electrical box 110 is mainly composed of plastic shells, tuning fork terminals 120, metal terminals, circuit boards, fuses, relays and other components, providing short-circuit or overload protection for automotive electrical appliances and wires to avoid car burnout. Such as Figure 1 to Figure 2 As shown, a tuning fork terminal 120 is inserted into the plastic shell of the automotive electrical box 110, and the tuning fork terminal 120 is a component used to realize electrical connection with a mating terminal (so-called male tab terminal) formed in the shape of a tab. known. [0003] The tuning fork terminal 120 has: a pair of crimping pieces 121, the end faces of which are spaced apart from each other and are arranged oppositely, and have a gap for inserting the mating termi...

AI Technical Summary

Problems solved by technology

[0004] The size of the crimping piece 121 of the tuning fork terminal is an important dimension. Once the size between the crimping pieces 121 exceeds the tolerance range, the connection function will fail

However, due to the complex structure, small size and high precision of the product 110; difficult mold making (about 800 inserts), injection molding is difficult to form, and the production process is easy to break due to high-speed mold insert pins, which is prone to insufficient injection molding, resulting in "meaty" products , Blockage of the tuning fork hole

The existing technology uses manual detection, which has low detection accuracy and slow efficiency. At the same time, because workers work for a long time, it is easy to miss the detection phenomenon. A detection device for unqualified products caused by "more meat" or "lack of meat"
